Hi!
I am experienced 3D artist, with years of experience working on projects like this one.
What I can provide you is high quality low poly model, with precise and flawless topology and mapping, so you can use it with any software package without any problems.
Time to complete project like this is typically 3-5 days, depending on number of revisions, and requirements.
Please, feel free to check out my portfolio, where you can see some samples of my work, and if you are interested, I can make a quick sample of your project, so you can see how it would look.
If you have any questions, please, don't hesitate to ask.
Best regards,
Jovan
